BELT TIGHTENING AN D CUTTING DEVICE.

Application filled November 27, 1922. Serial No. 603,6QQ,

To all whom it may concern I Be it'known that I, WALTER S. LAKE, acitizen of the United States, andresident of Kansas City, JacksonCounty, State of-Mis- -souri, have invented a certain new and usefulImprovement in Belt 'llghtening and Cutting Devices, of which thefollowing is a complete specification. This invention relates to belttightening, cutting and fastening devices and has for its object toproduce a device of the character mentioned which is so constructed andar-, ranged that thebelt may be properly tightcned, cut with anabsolutely square joint and then .abutted against the ot er end of thebelt and the two ends secured together by any suitable or preferredlacing;\all of theseoperations being carried out without removing thebelt from operative positibn'. v

A further object is to producea device of construction for convenienceof and which is construction. I

J With the objects namedin yiew the invention consists in certain noveland useful features of construction and organization of parts ashereinafter described and in order that it may be fully understood,reference is to be had to the accompanying portability; also of simpleand. inexpensive I drawings, in which Figure 1 is a top plan view of thedevice;

Figure 2 is a side view of the same;

Figure 3 is a section 0 the line III-I I I of Figure 2; p Figure i is asection on the line Il -*1" of Fi 'ure 3;

Figure 5 is a view similar to that of Fig ure 3, but illustrates thedevice as it will ap- Jearwhen a belt lacing of a preferred type hasbeen placed in the device;

Figure 6 is an end view of a common and a well known type of beltlacing; and

- ferred to.

Figure? is a top plan view of anew of belt lacing as it will appear whenengaged with a belt.

In the'said drawings, where like reference characters identifycorresponding parts in all of the figures, 1 illustrates the base mem:ber of the device, said base member being" formed with a longitudinalslot or opening 2 for the reception of a knife, hereinafter re-Projecting at ri ht angles the base and. at one end thereo is a handle 3for use in positioning thedevice, and at theother end,

. i I r V '9 and equipped at its and claimed type i the base member isformed with an upwardly projecting standard 4 terminating in a forwardlyextending arm 5 parallel to and above the base and ending at a pointabout midway the length of the base. v 3

The standard 4 is also formed with a air of arms 6 and 7 projecting in 0posits directions and curving around paral el to the base and atopposite sides and above the plane of the same.

The base 1 is formed at one side with an extension or abutment portion 8underlying the end of the arm 7.; At its'op'posite side, the base 1 isformed with a pair of outwardly projecting ears 9, between which issecured a roughened feed roller 10'keyed on an operating shaft 11,journaled in the ears outer end in close proximity to the handle 3 withan operating knob 12, whereby said. roller 10 may lie rotated.

Secured in the slot 2 of the base is a beltcutting knife '13 formedwith-air operating ear 14. The ear will at all tim s, project above thebase through the slot and the body of the knife is formed near; its endswith a pair of semi-circular slots 15 for engagement with a pair of pinsloispanning the slot 2. In this connection by reference to Figure 4, itwill be noted that-when the knife is in its elevated position, the pins16 will beengaged in a part of the slots. which is substantially atright an Ice to the vertical. It willtherefore. be evident that directdownward pressure on the knife will-be re- 1n position. W'hen. it isdesired to lower the knife a downward and rearward other arm 6 isengaged by a clamping sci'ew 20 provided with an operating, ikfn'ob 21at its upper end. Swiveled 'on the'flower, end of the screw 20 is aninvertegjU-shaped bracket 22 between the arms of '-,-whi(lh is journaleda roller 23 in length substantially equal .to the length of thecorrugated roller 10 and. adapted to clamp the belt 13 tightly -movementis imparted to it by the operator teeth, said clamping foot be'ngadapted to clamp one end of abeltB d' an upon the extension, 8 of thebase 1. he

down upon the feed roller 10, as will be describethiliereinbelow. "-Inorder to maintain the roller 10 in any predetermined position against'tle contracting tendency of the belt.

a ratchet pinion 16) is keyed on theshai't ll adjacent one of theearsi), and pivoted on one of said ears 9 is a gravity-pawl 10* inengagement with the ratchet;

T he extremity of the arm 5 i's-engaged by a clamping screw 24 carryingat its lower end a swiveled bracket 25 to which is seecured afpair ofclamping bars 26 and 27 spaced slightlyapart to provide aknifereceiving'slot 28 and of substantially the same length "as the baseI; said bars 26 and 27 being secured together at their ends by a pair ofcross straps 2!).

1 the bars; and 27 against rotation, the

rear strap .29 is notched to coincide with the slot 28 and receivedwithin said notch and'slot is'a guide tongue 30 formed on thefront-faceuot-the standard 4 (see Figure 4).

Keyed to the upperend of the screw 24 is an operating-Wheel 31 formedwith a serlcs of ratchet teeth 32. and provided also with a a pluralityof straight sided teeth 33. The wheel 31 is received withinthebi'fureatcd cnd of an operating handle 34 loosely jour naled on thescrew 24',and mounted between said bifurcated arms is adouble acting dog35p1voted'fo'r operation on a pint-36 formed at'its upper endwith aprojecting portion 37 for afpurpose'w'hich will hereinafter. appear.,b'ecured-, in the handle and spaced 'slightlyfrom the'pin'37 isa Secondpin 38 'formed with a projeetingkhead. The parts normally stand in theposition shown in Figure 1, the dogheing retained-in the position shownby means of a sprii g'flf) abutting at its rear end agai-nst 'the pin'38, in which position-the partsa're ready" to impartdown-' wardmovementto the clamping bars 26 and 27. Then it is desired to rotate the screw24 inth opposite dire .-tion for the purpose I of elevating, the ha 4end of tliespringtihtjs disengaged from the 26 and 27,. the free pin 38amliis-engaged with the pin 516.

'This action reverses the. tendency of the springeandcauses.the otherend of the dog to be depressed for engagement with any of the straightedged teeth i lf'i', as will be readi l v understood;

For convenience in maintaining" lacing devices of various kinds inposition pending their insertion into the extremitics of a bolt, thefollowing devlces are provided:

fipann-in ;the slot 28'and adapted for slid.-'

ing longitudinally on-bars 26-27 and rest 'ing thereon are a pair ofplan-s40; each forinedwitlna tongue 41=depending through the slot28,;said tongues. being-formed attheir lowerie'ndsw th flanges42respectively 'i'acing toward,ieach other; It willgbe evi" dent thatethos tianges 42- are adapted to I'QCQIVQ; between themselves andthefaces of In order to hold' ccived within the slot 28.

fing -12, for example, that illustrated in Fig ure (3; I In order tosecure the members 40 in position, they are pivoted near their rear.edges to av pair of securing clips 423 bent downwardly and engaged withthe underface of the bars 26 and 27, as willhe readily understood. Themen'ihers to are ordinarily slid to the extreme limits of their movementso as to be out of the way, as will be set forth inthe description ofthe operation of the deviuu'and when the kuiil'c is elevated and thebars 26 and :27 are lowered the plates 40 will be pivoted upwardly, theparts 41 and -12 being received Within the slot 28, through contact[with the edge of the knife.

In order-to securely maintain in position a belt lacing 42 formed of twomembers its end is adapted to intersect the slot 28 between the pair ofbars 26 and 27.

The hinge portion of the, type of lacing mentioned is inserted invthe-slot as (see Figure 5) and the lacing is securely rctained inposition under the pressure imposed on it by the thumb screw 44.

In the operation of the device one end of the belt is inserted intoposition with its end flush with the slot 2 of the base and is clampedtightly in such position through the pressure in'iposcd on it hy tbeclamping foot 19 of the screw 17, against the cxtcnsion 8 of the base.

The-other end of the belt is inserted between the rollers 10 and 23, andclamped tightly between said'rollers by operation of the clamp screw 20.The feed roller is now rotated through its knob l2, thus stretching thebelt and causing the adjusted end to overlap the other end, as shown inFig ure 3, the pawl and ratchet mechanism 10* and 10* holding theadjusted end firmly in the position above referred to.

The knife is now elevated through application of forward and upwardpressure on its ear 14;, and when in fully elevated posi tion projectsabove the end of the belt which overlies the extension 8 and underliesthe overlai iping end of the belt; (see Figure 3?). The clamping screw24 is now rotated by means of its handle 34, the dog 35 engaging theteeth 32, and the clamping bars 26 and 27 exert clamping pressure on the,belt at opposite sides of the knife, causing the knife to impinge onthe belt with a shearing action and severing the extremity otsaid beltaccuratelyand smoothly, the knife being rclrcliniinary to the downwardmovement of the bars iii and 27. the lacing supports 40 aren'iovcd tothe opposite ends of the slot 29, and upon downward movement of saidbarsfthe tongues I lit!
